In daily life, we often see the use of a non-woven product in road maintenance. What is the principle behind this? This kind of product is also called the highway maintenance non-woven fabric by our image. In fact, this non-woven fabric product belongs to a needle punched non-woven fabric(road maintenance nonwovens factory) process. The principle of using air flow greatly increases the mutual entangling and bonding between individual fibers and increases the relative stretching ability. What is the principle of using such nonwovens in road maintenance? Please see below for your analysis.
 
Road maintenance of non-woven fabrics is an option. The concrete in highways interacts with non-woven materials(road maintenance nonwovens manufacturer) to form a good impervious material, and its impervious effect depends entirely on the impervious effect of non-woven fabrics. At present, the most widely used anti-seepage materials for domestic road maintenance are polyvinyl chloride and polyethylene, which are all flexible materials for polymer chemistry. The specific gravity is relatively small, and their extensibility is very strong. Their adaptability is also very high. However, because of this, the non-woven fabrics used for highway maintenance have better water absorption and water retention than this material, making concrete more durable and more durable.

Secondly, highway maintenance non-woven fabrics have very clear air permeability and water permeability. When the water flow passes through, the loss of sand can be effectively avoided. It is very easy to use and the construction is very simple. At present, it is widely used in chemical, construction, waste treatment plants and other fields. From this we can see that the use of non-woven fabrics(road maintenance nonwovens on sales) in road maintenance is more appropriate and more effective than the use of plastics and other materials.
